What are the differences between lithium batteries and lead-acid batteries for electric vehicles?

The cycle life of lead-acid batteries is about 200 times, and the highest is 300 times. The lithium battery has a cycle life of more than 300 times, and it can be used for standard charging (5 hours rate) up to 500 times or even more than 1000 times. Lead-acid batteries can be used for 1-1.5 years at most, while lithium batteries can be used for 3 years under the same conditions. 2. Safe to use and good performance Lithium batteries completely solve the potential safety hazards of lead-acid batteries. Lead-acid batteries will explode under a strong collision, posing a threat to the lives of consumers. The lithium battery does not explode under strict safety tests. 2. No memory effect Rechargeable batteries work under the condition that they are often fully charged, and the capacity will quickly fall below the rated capacity value. This phenomenon is called the memory effect. The lithium battery does not have this phenomenon. No matter what the state of the battery is, it can be charged and used at any time, without having to discharge it before charging. 4. Small size, light weight and long time. The volume of a lithium battery with the same specification and capacity is 2/3 of the volume of a lead-acid battery, and its weight is 1/3 of the lead-acid battery. Electric cars are twice as expensive. 6. Green and environmentally friendly lead-acid batteries There are a lot of lead in lead-acid batteries in electric vehicles. If they are not properly disposed of after being discarded, they will pollute the environment. Lithium materials do not contain any toxic and harmful substances and are regarded as green batteries in the world. The battery has no pollution during processing and use, and has become a hot research topic. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
